In the interest of convenience and fewer selling headaches, I figured I'd post my question in the MBP section of the forum; undoubtedly, the Air folk would do their best to proselytize me to a rarefied computing experience. In March, not long after the MBP line went to Sandy Bridge, I purchased the computer on which I'm typing this post, 2.3 i5. As some of you may know, I'm looking into outfitting my rig with a 128 SSD (most likely Crucial M4). Up until a few minutes ago, I hadn't really looked at the prices of the latest Air-lineup. I was quite surprised that the base 13-inch model, only $100 more than the 13-inch, comes with 128GB of flash storage (sufficient for my needs). The wheels have begun to turn in my head. Given my computer is less than a half year old, why not sell it for 900-1000$ then put the SSD money towards the difference. Since the last Air iteration, one grievance I've had with Apple is that they have opted to make the Air line more professional than the "Pro" line. Brighter & higher-resolution screen, flash storage, etc. It continues with this iteration. Plus, I'd get Lion. However, two things are precluding me from proceeding: A) My MacBook Pro (while still relatively new) has a few exterior scratches and screen smudges which may hurt its resale value. B) You're stuck with only 4GB of RAM on the Air. While 4 gigs is the standard right now, as I intend to keep the computer for many years, it won't be long before 8 gigs is obligatory. Any thoughts? Thanks!
